Abstract:     A method and system for correcting misrecognized phrases in a computer speech recognition system prevents prior misrecognized text phrases from reoccurring during re-dictation. In particular, the present invention provides a method for correcting a user identified misrecognized text at a location in a dictated electronic document. The method includes: receiving dictation from a user; processing the user input to identify a plurality of alternate text selections; excluding the misrecognized text from the plurality of alternate text selections; and replacing it with a replacement text. These steps are repeated each time the user selects and re-dictates text at the location of the misrecognized text.
